Hello all, I'm primarily a gig photographer and as such use available light. Recently I've noticed that I'm having to go to max ISO of 1600 whereas I've been able to get quality images from an ISO of half that or less. I mainly use a 30D which I've had from new (7yrs) so know exactly how it's been treated . Any ideas, or is it just age? I love this piece of kit and am loathe to upgrade.Paul

Hi, Rorschach none of the above I'm afraid I was at a bike rally last weekend and the lighting was superb the same as last year when I shot the same rally. I usually shoot wide open at about a 60th all my glass has image stabilisation so frankly I'm stumpedRegardsPaul
